-h server-name
Specifies a whois server other than the default server
rs.internic.net.
name
The name parameter represents the user ID, host name, network
address, or nickname on which to perform a directory search.
When you follow the name with the optional three periods (...),
the whois command performs a wildcard search for any name that
matches the string preceding the three periods.
The name argument can specify any of the following.
o The name of the registered user.
o The name of a registered Internet host.
o The name of some other entity recognized by the whois
server. By default, the whois command queries the host
rs.internic.net.
The parameters specified to the whois command are concatenated
together (separated by white space) and presented to the whois
server. The default action, unless directed otherwise with
a special name, is to do a very broad search, looking for
matches to name in all types of records and most fields (such
as name, nicknames, host name, and network address) in the
database.
